  • According to a third aspect, a mobile terminal is provided in implementations of the disclosure. The mobile terminal includes an AP, a touch display screen, a fingerprint recognition device, and a memory configured to store one or more programs. The fingerprint recognition device has a fingerprint recognition area in a first area of the touch display screen. The one or more programs are configured to be executed by a processor including the AP and include instructions configured to execute the following.
  • The touch display screen is controlled to instruct the fingerprint recognition device to collect fingerprint data of a user upon detecting a first touch operation of the user in the first area. The fingerprint recognition device is controlled to collect the fingerprint data and to send the fingerprint data to the AP. The fingerprint data is compared with preset fingerprint template data in the mobile terminal with the AP, and the touch display screen is lighted up and a lock-screen interface is unlocked, with the AP, when the fingerprint data is matched with the fingerprint template data.
  • According to a fourth aspect, an apparatus for controlling unlocking is provided in implementations of the disclosure.

    DETAILED DESCRIPTION
  • In order for those skilled in the art to better understand technical solutions of the present disclosure, in the following, technical solutions of implementations of the present disclosure will be described clearly and completely with reference to accompanying drawings in implementations of the present disclosure. Apparently, implementations described hereinafter are merely some implementations, rather than all implementations, of the present disclosure. All other implementations obtained by those of ordinary skilled in the art based on implementations of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
  • The terms "first", "second", and the like used in the specification, the claims, and the accompany drawings of the present disclosure are used to distinguish different objects rather than describe a particular order. In addition, the terms "include", "comprise", and "have" as well as variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus including a series of steps or units is not limited to the listed steps or units. Instead, it can optionally include other steps or units that are not listed; alternatively, other steps or units inherent to the process, method, product, or apparatus can also be included.
  • The term "implementation" referred to herein means that a particular feature, structure, or character described in conjunction with the implementation may be contained in at least one implementation of the present disclosure. The phrase appearing in various places in the specification does not necessarily refer to the same implementation, nor does it refer to an independent or alternative implementation that is mutually exclusive with other implementations. It is explicitly and implicitly understood by those skilled in the art that an implementation described herein may be combined with other implementations.
  • A mobile terminal in implementations of the disclosure may include various handheld devices, in-vehicle devices, wearable devices, computing devices that have wireless communication functions or other processing devices connected to the wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), terminal devices, and the like. For the convenience of description, the above-mentioned devices are collectively referred to as the mobile terminal. Hereinafter, implementations of the disclosure will be described in detail.
  • FIG. 1A is a schematic structural diagram illustrating a mobile terminal 100 according to an implementation of the present disclosure. The mobile terminal 100 includes an application processor (AP) 110, a touch display screen 120, and a fingerprint recognition device 130. The fingerprint recognition device 130 is coupled to the touch display screen 120 and has a fingerprint recognition area in a first area of the touch display screen 120. The AP 110 is coupled with the touch display screen 120 and the fingerprint recognition device 130 via a bus 150.
  • The touch display screen 120 is configured to instruct the fingerprint recognition device 130 to collect fingerprint data of a user upon detecting a first touch operation of the user in the first area.
  • In an example, the first area is any preset area of the touch display screen 120 and locates on an upper left side (as illustrated in FIG. 1B), an upper side, an lower side, an left side, or an right side of the touch screen display 120, which is not limited herein.
  • The fingerprint recognition device 130 is configured to collect the fingerprint data and send the fingerprint data to the AP 110.
  • The AP 110 is configured to compare the fingerprint data with preset fingerprint template data in the mobile terminal, and to light up or turn on the touch display screen 120 and unlock a lock-screen interface when the fingerprint data is matched with the fingerprint template data.
  • According to this implementation, when the first touch operation in the first area is detected, the touch display screen of the mobile terminal instructs the fingerprint recognition device to collect the fingerprint data. The fingerprint recognition device collects the fingerprint data and sends the fingerprint data to the AP. The AP compares the fingerprint data with the preset fingerprint template data in the mobile terminal, and lights up the touch display screen (that is, the whole touch display screen) and unlocks the lock-screen interface when the fingerprint data is matched with the fingerprint template data. As such, the mobile terminal can accurately identify the first touch operation of the user in the first area in which the fingerprint recognition device locates, and then instruct the fingerprint recognition device to collect the fingerprint data. In this way, it is possible to prevent a touch operation of the user on an area other than the first area from accidentally triggering the fingerprint recognition device to collect the fingerprint data, which is beneficial to improving the accuracy and intelligence of the fingerprint unlocking of the mobile terminal.
  • In an implementation, the touch display screen 120 is further configured to wake up both the AP 110 and the fingerprint recognition device 130 and to instruct the AP 110 to light up the first area, upon detecting a second touch operation of the user in a second area. The second area is an area of the touch display screen 120 other than the first area. The mobile terminal is in a screen-off state and a touch screen of the touch display screen 120 is in a waked state.
  • The AP 110 is further configured to light up the first area of the touch display screen 120. The first area lighted up is configured to guide a fingerprint enrollment operation of the user.
  • The fingerprint enrollment operation is the first touch operation in the first area.
  • The first area is smaller than the second area.
  • According to this implementation, when the second touch operation of the user in the second area is detected, the touch display screen of the mobile terminal first wakes up the AP and the fingerprint recognition device and instructs the AP to light up the first area. The AP then lights up the first area, where the first area is configured to timely remind the user of a location of the fingerprint recognition device for enrollment of fingerprint data, and the second area is the area of the touch display screen other than the first area. As such, the mobile terminal provides a trigger mechanism for an initialization process of fingerprint unlocking, where the initialization process of fingerprint unlocking refers to waking up the AP and the fingerprint recognition device, and reminding the user of the location of the fingerprint recognition device by lighting up the first area. With such trigger mechanism, when the mobile terminal is in the screen-off state, there is no need to consume power to continuously wake up the AP and the fingerprint recognition device. Since the first area is smaller than the second area, the second area can be conveniently touched by the user, thereby triggering the initialization process of fingerprint unlocking of the mobile terminal in the screen-off state. In this way, it is possible to improve the convenience of triggering the initialization process of fingerprint unlocking of the mobile terminal and the efficiency of power management. In addition, since the AP and the fingerprint recognition device are waked up synchronously, compared with waking up the AP and the fingerprint recognition device sequentially, time can be saved, which is advantageous for further improving the speed of fingerprint unlocking of the mobile terminal.
  • In an example, the touch display screen 120 includes a touch screen and a display screen. The touch screen is stacked on the display screen, that is, the display screen is disposed at a lower side of the touch screen. The fingerprint recognition device 130 includes a fingerprint sensor, where the fingerprint sensor includes at least one of: an optical fingerprint sensor, a capacitive fingerprint sensor, an ultrasonic fingerprint sensor, and the like.
  • In the case that the fingerprint sensor is a capacitive fingerprint sensor and the touch screen of the touch display screen is a capacitive touch screen, the fingerprint recognition device is coupled to the touch display screen as follows. The fingerprint recognition device is integrated into the touch screen of the touch display screen; specifically, a first sensing capacitor array of the fingerprint recognition device may be embedded in a second sensing capacitor array of the touch screen, and sensing capacitors of the first sensing capacitor array are evenly distributed in the first region.
  • In the case that the fingerprint sensor is an optical fingerprint sensor, the fingerprint recognition device is coupled to the touch display screen as follows. The fingerprint recognition device is integrated into the touch display screen. The fingerprint recognition device of the mobile terminal collects the fingerprint data of the user based on the principle of pinhole imaging. The touch screen and the display screen of the touch display screen have a spacing layer therebetween and the spacing layer is provided with a first pinhole array layer in a first preset area. The display screen has a driving circuit layer , which is provided with an evenly distributed pinhole array in a second preset area at print stage. The evenly distributed pinhole array on the driving circuit layer serves as a second pinhole array layer. The first pinhole array layer has light transmission holes that are in one-to-one correspondence with light transmission holes of the second pinhole array layer. The optical fingerprint sensor includes a charge-coupled device (CCD) array layer, and the CCD array layer is configured to detect light transmitted through the first pinhole array layer and the second pinhole array layer. The first preset area and the second preset area both correspond to the first area.
  • In the case that the fingerprint sensor is an ultrasonic fingerprint sensor, the fingerprint recognition device is coupled to the touch display screen as follows. Under the first area of the touch display screen, a vacuum detecting chamber is disposed. In the vacuum detecting chamber, multiple ultrasonic sensors are evenly arranged. The ultrasonic sensor includes an ultrasonic signal transmitter and an ultrasonic signal receiver, where the ultrasonic signal transmitter is configured to transmit a signal of a specific frequency to detect a fingerprint of the user and the ultrasonic signal receiver is configured to receive a reflected echo signal. The ultrasonic wave has an ability of transmitting the material and produces different echoes of different sizes depending on the material (when the ultrasonic wave reaches surfaces of different material, it is absorbed, transmitted, and reflected to different extents). With the above, the ultrasonic sensor can distinguish positions of ridge and valley of a fingerprint of a finger of the user.
  • The display screen can be a thin film transistor-liquid crystal display (TFT-LCD), a light emitting diode (LED) display, an organic light-emitting diode (OLED) display, or the like.
  • In an implementation, as illustrated in FIG. 2A, the mobile terminal 100 further includes a display microcontroller unit (MCU) 160. The display MCU 160 is coupled to the touch display screen 120.
  • In terms of comparing the fingerprint data with the preset fingerprint template data in the mobile terminal and lighting up the touch display screen when the fingerprint data is matched with the fingerprint template data, the AP 110 is configured to instruct the display MCU 160 to compare the fingerprint data with the preset fingerprint template data in the mobile terminal, and to light up the touch display screen 120 when the fingerprint data is matched with the fingerprint template data.
  • In terms of lighting up the first area of the touch display screen, the AP 110 is configured to instruct the display MCU 160 to light up the first area of the touch display screen 120.
  • According to this implementation, the display MCU of the mobile terminal can cooperate with the AP to perform recognition of the fingerprint data and lighting up the touch display screen during controlling unlocking, compared with the case that the AP processes all operations, long time consumption and low efficiency can be avoided, which is beneficial to improving the efficiency of controlling unlocking of the mobile terminal.
  • In an implementation, as illustrated in FIG. 2B, the mobile terminal 100 further includes a memory 140. The memory 140 is configured to store a lock-screen application and an Android system. The Android system includes a FingerprintService and a power manager service (PMS). The AP 110 is coupled with the memory 140 via the bus 150.
  • In terms of comparing the fingerprint data with the preset fingerprint template data, and lighting up the touch display screen 120 and unlocking the lock-screen interface when the fingerprint data is matched with the fingerprint template data, the AP 110 is configured to: invoke the FingerprintService to compare the fingerprint data with the preset fingerprint template data in the mobile terminal, and invoke the PMS to light up the touch display screen 120 and the lock-screen application to unlock the lock-screen interface when the fingerprint data is matched with the fingerprint template data.
  • In this implementation, the AP 110 is further configured to wake up the PMS before the AP 110 lights up the first area of the touch display screen 120.
  • According to this implementation, before lighting up the first area of the touch display screen 120 (that is, before comparing the fingerprint data with the preset fingerprint template data), the AP of the mobile terminal can wake up the PMS. In this way, when the fingerprint data is matched with the preset fingerprint template data, the AP can light up the touch display screen with the PMS in a waked up state already, without waiting the PMS to be waked up, thereby saving time for waiting the PMS to be waked up. It is possible to improve the speed of fingerprint unlocking with the screen lighted up triggered by the first touch operation of the user in the first area.
  • In an implementation, the first touch operation in the first area is an operation of touching the first area for a duration greater than a preset duration threshold.
  • According to this implementation, the first touch operation is the operation of touching the first area for the duration greater than the preset duration threshold. It can be seen that, the first touch operation is not a general touch operation such as a single click. As such, it is possible to prevent, to some extent, an accidental general touch operation of the user in the first area from triggering collection of the fingerprint data, and ensure that the fingerprint data is collected by the fingerprint recognition device only when a fingerprint of a finger of the user is stably contacted with the first area. In this way, the fingerprint recognition device can collect the fingerprint data at appropriate time and the fingerprint data collected can be reliable, which is beneficial to improving the accuracy of fingerprint unlocking.
  • In an example, the second touch operation in the second area is: a single-touch operation or a click-touch operation in the second area for consecutive N times within a preset duration, where N is an integer greater than 1; a touching-and-sliding operation in the second area for a distance greater than a preset distance threshold; a touching-and-sliding operation in the second area in a graphic matched with a preset graphic; or a pressing operation in the second area in a force greater than a preset strength threshold.
  • According to this implementation, the second touch operation is the single-touch operation in the second area for consecutive N times within the preset duration, the touching-and-sliding operation in the second area for the distance greater than the preset distance threshold, the touching-and-sliding operation in the second area in the graphic matched with the preset graphic; or the operation of pressing the second area in the force greater than the preset strength threshold. It can be seen that, the second touch operation is not a general touch operation such as a single click. As such, it is possible to avoid, to some extent, unnecessary power consumption of the mobile terminal due to continuously waking up the AP and the fingerprint recognition device by frequent general touch operations of the user on the touch display screen. It is thus beneficial to reducing power consumption and improving power efficiency of the mobile terminal.
  • FIG. 3 is a schematic flow chart illustrating a method for controlling unlocking according to an implementation of the present disclosure. The method is applicable to a mobile terminal. The mobile terminal includes an application processor (AP), a touch display screen, and a fingerprint recognition device. The fingerprint recognition device is coupled to the touch display screen and has a fingerprint recognition area in a first area of the touch display screen. As illustrated in FIG. 3, the method begins at S301.
  • At S301, the mobile terminal controls the touch display screen to instruct the fingerprint recognition device to collect fingerprint data of a user upon detecting a first touch operation of the user in the first area.
  • At S302, the mobile terminal controls the fingerprint recognition device to collect the fingerprint data and to send the fingerprint data to the AP.
  • At S303, the mobile terminal compares, with the AP, the fingerprint data with preset fingerprint template data in the mobile terminal, and when the fingerprint data is matched with the fingerprint template data, lights up, with the AP, the touch display screen and unlocks, with the AP, a lock-screen interface.
  • The fingerprint template data refers to reference fingerprint data used for identifying an identity of the user and can be enrolled by the user in advance. The "comparing" refers to comparison of the fingerprint data and preset fingerprint template data, and a result of the comparison can be "matched" or "not matched".
  • According to the implementations of the disclosure, the fingerprint recognition area of the fingerprint recognition device of the mobile terminal is in the first area of the touch display screen. When the first touch operation of the user in the first area is detected, the touch display screen of the mobile terminal instructs the fingerprint recognition device to collect the fingerprint data. The fingerprint recognition device collects the fingerprint data and sends the fingerprint data to the AP. The AP compares the fingerprint data with the preset fingerprint template data, and lights up the touch display screen and unlocks the lock-screen interface when the fingerprint data is matched with the fingerprint template data. As such, only when the first touch operation in the first area is detected, the touch display screen of the mobile terminal will instruct the fingerprint recognition device to collect the fingerprint data; otherwise, if a touch operation of the user on an area of the touch display screen other than the first area is detected, the touch display screen will not instruct the fingerprint recognition device to collect the fingerprint data. In this way, it is possible to prevent the touch operation on the area other than the first area from accidentally triggering the fingerprint recognition device to collect the fingerprint data, which is beneficial to improving the accuracy and intelligence of the fingerprint unlocking of the mobile terminal.
  • As an implementation, the following is further performed.
  • The mobile terminal controls the touch display screen to wake up both the AP and the fingerprint recognition device and to instruct the AP to light up the first area, upon detecting a second touch operation of the user in a second area. The second area is an area of the touch display screen other than the first area.
  • The mobile terminal lights up, with the AP, the first area.
  • According to this implementation, when the second touch operation of the user in the second area is detected, the touch display screen of the mobile terminal first wakes up the AP and the fingerprint recognition device and instructs the AP to light up the first area. The AP then lights up the first area, where the first area is configured to timely remind the user of a location of the fingerprint recognition device for enrollment of fingerprint data, and the second area is the area of the touch display screen other than the first area. As such, the mobile terminal provides a trigger mechanism for an initialization process of fingerprint unlocking, where the initialization process of fingerprint unlocking refers to waking up the AP and the fingerprint recognition device, and reminding the user of the location of the fingerprint recognition device by lighting up the first area. With such trigger mechanism, when the mobile terminal is in the screen-off state, there is no need to consume power to continuously wake up the AP and the fingerprint recognition device. Since the first area is smaller than the second area, the second area can be conveniently touched by the user, thereby triggering the initialization process of fingerprint unlocking of the mobile terminal in the screen-off state. In this way, it is possible to improve the convenience of triggering the initialization process of fingerprint unlocking of the mobile terminal and the efficiency of power management. In addition, since the AP and the fingerprint recognition device are waked up synchronously, compared with waking up the AP and the fingerprint recognition device sequentially, time can be saved, which is advantageous for further improving the speed of fingerprint unlocking of the mobile terminal.
  • In an implementation, the mobile terminal further includes a memory, storing a lock-screen application and an Android system. The Android system includes a FingerprintService and a power manager service (PMS).
  • The mobile terminal compares, with the AP, the fingerprint data with the preset fingerprint template data in the mobile terminal, and lights up, with the AP, the touch display screen and unlocks, with the AP, the lock-screen interface when the fingerprint data is matched with the fingerprint template data as follows.
  • The mobile terminal invokes, with the AP, the FingerprintService to compare the fingerprint data with the preset fingerprint template data in the mobile terminal, and invokes, with the AP, the PMS to light up the touch display screen and the lock-screen application to unlock the lock-screen interface when the fingerprint data is matched with the fingerprint template data.
  • As an implementation, before lighting up, with the AP, the first area of the touch display screen, the mobile terminal further wakes up, with the AP, the PMS.
  • According to this implementation, before lighting up the first area of the touch display screen 120 (that is, before comparing the fingerprint data with the preset fingerprint template data), the mobile terminal can wake up, with the AP, the PMS.
